Prelude L4-2056cc DOHC (1990)
Starter Motor: Testing and Inspection
Ensure that air temperature is between 59 and 100° before testing.
1.
Connect a suitable battery-starter tester according to manufacturers instructions.
Fig. 4 Distributor 2-P Connector Location
2.
On Prelude models, disconnect coil wire at distributor and connect it to a suitable ground.On Accord models, disconnect 2-P connector from
distributor, Fig. 4.
3.
On all models,press clutch pedal to floor and turn ignition switch to start position. If starter does not crank engine, check battery condition, battery
positive wire, ground and wire connections for looseness or corrosion.
4.
If starter still does not crank engine, by-pass ignition switch circuit as follows:
a. On Prelude models, disconnect BLK/WHT wire from solenoid terminal on starter.On Accord models, disconnect BLK/RED wire from
solenoid terminal on starter.
b. On all models, connect a jumper wire from battery positive terminal to solenoid terminal.
c. If starter cranks engine, check for an open in BLK/WHT or BLK/RED wire circuit between starter and ignition switch. If circuit is satisfactory,
check connectors and ignition switch.
d. On automatic transmission models, check neutral safety switch and connector.
e. On manual transmission models, check starter relay, clutch interlock switch and connectors.
5.
If starter still does not crank engine, remove and diagnose for internal problems.
6.
Check voltage and current draw, then compare as follows:
a. Cranking voltage should be no less than 8 volts and current draw should not be more than 350 amps.
b. Engine speed when cranking should be above 100 RPM. If engine speed is not at least 100 RPM, check for loose battery or starter terminals,
worn starter brushes, open circuit in commuter segments, dirty or damaged helical spline or drive gear, and defective drive gear overrunning
clutch.
7.
Check for starter disengagement as follows:
a. On models with manual transmission, press clutch pedal to floor.
b. On all models, turn ignition switch to start and release to run.
c. If starter drive gear hangs up on flywheel or flex plate, check solenoid plunger and switch for malfunction or drive gear assembly for dirty or
damaged overrunning clutch.
